Considering the fact SEGA's been destroying itself and restructuring their games, I don't find this surprising.
It's not like SEGA makes a whole lot of new things anyway. They probably just haven't announced anything yet. There's sure to be more 3DS titles eventually.@Pichu2010
With what logic? Sonic 4 Episode 2 and Sonic Racing 2? Which will probably both be on Wii U?
Good thing Wii and DS have so many exclusive Sonic titles, moreso than the HD consoles. But I guess those never count.
